Seriously? 8-bit non-color managed übersharpened original... I really hope you are not serious, as a joke this is quite fun thou.
I\'ll see what can be done later tonight, if I figure out how to do gamma 1.0 processing with gamma 1.8-2.5 image (hard to eyeball what gamma you have used on your non-color managed image) without assigning some ICC to it (since then my image would look different than any other image). This nightmare will be blast from past, I have been having fully color managed workflows almost decade now...back to 90\'s
It is not a joke, just a comparison of methods using the same input image - not necessarily ideally prepared for any particular method.
I saved four of the images with Lightroom, which I only recently started to use. I did not even realize that it applies sharpening by default. In the camera I have set zero sharpening, which DPP automatically adopts but LR apparently not. The basket was taken from an existing TIFF file that was indeed sharpened for the large format.
Concerning the 8 bits, that is the result from starting with an 8-bit ring chart and the fact that it does not matter for my processing, but I will happily provide you with 16 bits.
Here is a new version. The originals were saved as 16-bit TIFF files from LR4 with all sharpening options set to zero.
It was a pain to crop the images to precisely the same pixels as yesterday, and an even greater pain to figure out the precise formula for the ring chart (which I took from this site) but now even the ring chart is a 16-bit original. Of course, after all this pain I expect you to demonstrate that you need 16 bits.
I can\'t help you with color management, because I don\'t do color management.
Edit. Hmm. I see now that saving 16-bits with Matlab gives a 16-bit TIFF file with only 8 real bits.
I removed the file and will try to fix it later.
